ULTRASHORT WAVE OSCILLATION GENERATION Filed July 28, 1930 INVENTOR CLARENCE W. HANSELL ATTORNEY for the reason that radiation from the container is least directive in a plane perpendicular to its longitudinal axis. If desired, the reflector and container may be immersed in a liquid identical With the main body of the liquid of the solution.

The colloidal solution need not be placed Within a cylindrical container, but may be placed Within a container of parabolic form of either glass or quartz as shown in Figures 3 and 4 under suitable pressure by means of a suitable valve 12. The parabolic surface of the container 14 of Figures 3 and 4 is preferably silvered or sputtered with a metal coating so as to cause eiiicient reiiection of the oscillations.

In order to provide for the elongation and continuous change of path of the discharge between electrodes 15, i8 suitably supported Within the solution, an electrical field may be applied to the discharge in a direction traversing its general longitudinal axis, by means of electrodes 20, 22 to which suitable potentials may be applied, either direct or alternating through leads 24,

A disruptive or short circuiting discharge may also be used to produce ultrashort Waves by replacing electrodes 20, 22 by electromagncts, the magnetic field produced thereby being passed through the solution and being sufficient to cause the discharge to wobble or grapevine itself through the solution so that it engages a continuously changing set of particles. With a magnetic eld, the grapevining effect is increased ii iron or any other magnetic substance is used for the particles in the colloidal solution.
